      Aries gives developers a finance API built for real trading products, not just demo data.
      You can use one platform for live market data, order execution, account information, portfolio
      views, and supplemental financial datasets. If you are building brokerage experiences,
      trading tools, market dashboards, or AI workflows that need financial actions, Aries gives
      you the core API surface in one place.
